Finally appear to have sorted a "Data corruption-Loss" i was having with a 200 gig disk.
This is the bit i was missing .W2k with SP3 but no registry entry.Hope ive got it sorted.Also had massive datacorruption- loss due to a bad power connector and the drive not booting properly .This never happened with older drives!

Windows 2000 supports 48-bit LBA with Service Pack 3. You must also have a 48-bit LBA compatible BIOS and add or change a value in the Windows registry. The following are the major issues involving 48-bit LBA and Windows 2000:

Service Pack 3. To use a 48-bit LBA hard drive with Windows 2000 you must upgrade to Service Pack 3 or greater. If Windows 2000 is already installed you can use Windows Update to install SP3. If you are doing a new install of Windows 2000 make sure the installation CD is labeled "Including Service Pack 3" and note that Windows 2000 SP3 install has a problem where it does not support creating partitions greater than 137 GB. Refer to paragraph below Windows 2000 install does not support creating partitions greater than 137 GB.

EnableBigLba registry value. To enable 48-bit LBA support with Windows 2000 you must add or change the EnableBigLba registry value to 1 in the Windows registry. Simply upgrading and installing Service Pack 3 does not enable this registry value by default. For instructions on how to add EnableBigLba to the Windows registry,
Manual Method:
To enable EnableBigLba in the Windows registry, perform the following steps:

# Start a registry editor (e.g., regedit.exe). In Windows, click on Start->Run, enter "regedit".
# Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\atapi\Parameters registry subkey.
# From the Edit menu, select New, DWORD Value.
# Enter the name EnableBigLba, then press Enter.
# Double-click the new value, set it to 1, then click OK.
# Close the registry editor.
# Restart the machine for the change to take effect.
